5 ways to improve voting security in the US

With the U.S. presidential election just weeks away, questions about election security continue to dog the nation's voting system.

It's too late for election officials to make major improvements, "and there are no resources," said Joe Kiniry, a long-time election security researcher.

However, officials can take several steps for upcoming elections, security experts say.

"Nobody should ever imagine changing the voting technology used this close to a general election," said Douglas Jones, a computer science professor at the University of Iowa. "The best time to buy new equipment would be in January after a general election, so you've got almost two years to learn how to use it."
